This invention relates to railway structhe metal, of course, to be of rust resisting tures. It has for its objects to produce a character and possessing the requisite simple and comparatively inexpensive, yet strength for durability and safety. The tie practically eflicient, safe and durable track may be produced in different shapes, both tie and rail fastening means, and to attain crosswise and longitudinally, and be relativecertain advantages as will hereinafter more 1y light in Weight by eliminating all excess or f ll a ar, unnecessary material and making it rigid by The invention consists in the novel metallic Suitably flanging and ribbing the structure structure and 'in the parts and combinations As shown, the tie l is substantially inverted 1' and arrangements of parts hereinafter speci- T-shaped in cross SGCtiOnthIOHghOUt its midfied and aft rward ointed ut with ardle portion, or, in other words, it has a base ticularity in the appended claims. flange 2 and a central upstanding longitudinal In the accompanying drawings forming rib or flange 3.

Figure 4 is a face view of the rail seat pad Ali the ends of the blocks 10 are p detached to show the details thereof; and flanges 12 Which v e the base fla ges Of 35: Figure 5 is a, fragmentary view, on an the rails 8 in rather snug contact therewith, enlarged scale, partly in section and partly i while below said portions 12'are lugs 13 which side elevation, to illustrate the correlation and underlie said base flanges of the rails and co-action of the rail base, seat pad and fasten are preferably spaced, at least slightly, therelIlgblOCk, from, as more clearly shown in Figure 5 of 40 Referring now to the drawings, the nuthe drawings, as'at 14, in order to permit meral 1 designates generally the cross tic, limited downward movement of the rails 8 which, according to the present invention, without the latter coming in contact thereis preferablyconstructed throughout of metal with. and may be produced by any approved method In each of the blocks 10 is an aperture for 45 such as casting, rolling, forging or pressing; the reception of a securing bolt or screw 15,

v the rail. This pad is preferably composed tion of the elements which latter, as shown in the drawings, is inserted into a screw-threaded aperture provided therefor in the body of the tie.

Preferably, a pad 16 is interposed between the base flange of the rail 8 and the bottom of the channel or seat portion 7 of the tie 1, so as to serve as a sound deadener and cushion for of'a characteristic metal or alloy different from that of which the body of the tie 1 is composed and possessing a certain amount of inherent resiliency and sound deadening qualities and yet being capable of withstanding the usage to which it is put in the structure and'being resistant to the corrosive ac- As shown more clearly in Figure 4 of the drawings, this pad 16 is of general rectangular form, but it is provided at its opposite side mar inal portions'with notches 17, into which notc es are received the lugs 13 of the blocks 10, by which arrangement the pad is securely held from endwise movement in the channel or seat portion 7 of the tie. In this connection, it may be here stated that by the provision of the clearance space 14 between the lug 13 of the block 10 and the under side of the base flange of the rail 8, the latter always rests solely on the pad 16 even should a certain amount of wear occur due to the action of the rail on the paid under the weight of the trains passing thereover, and this clearance, of course, is provided principally to permit the pad to function yieldably as a cushion under the same conditions.

' By the peculiar formation of the fastening blocks 10 they are easily inserted into the sockets 9 by first placing the pad 16 in the channel or seat portion 7 of the tie, setting the rail in place thereon,thence placing the black with its lip portion 12 on top of the base flange of the rail at an angle and then sliding it'forward and at the same time dropping the bevelled endportion 1-1 of the block, during which manipulation the lug 13 enters the notch 17 in the pad 16 and underlies thebase flange of the rail, and when the block is final ly seated in the socket 9 the bolt or screw 15 is applied to hold the block in place. Preferably, a suitable lock-washer 18 is interposed betweenthe head of the bolt or screw and the top faceof the block 10 so as to resist any action tending to loosen; the bolt or screw. lVhile the side faces of the block 10 may be substantially perpendicular or square with the top and bottom faces thereof it is preferable to slightly taper or bevel the side faces in order to facilitate the placing of the block in and removing it from the socket 9, the side spondingly inclined.

walls of said socket, of course, being corre- On opposite sides of the sockets 9'the tie 1 may be provided with recesses 19, which, as shown, are rounded out, but they obviously may be of other form. These recesses afford clearance for convenience in applying tongs or other suitable implements to remove the blocks from the sockets. 7

It is to be particularly'noted that when the blocks 10 are in place in their respective sockets the track rails 8 are securely held against tilting laterally owing to the interlocking therewith of the projections 12 and 13 of the blocks 10 and the fact that the adjacent squared end portion of the block bears against the corresponding square end portion of the socket 9. This relieves the securing bolts or screws 15 of considerable strain. At the same time, when the securing bolt or screw 15 is removed it is a very easy matter to remove the ilqlock 10 by lifting its beveled end portion 11 rst.

From the foregoing it is clearly apparent and obvious that a simple and practical structure is produced which has all the advantages of the ordinary wooden and metallic ties and considerable further advantage thereover.

Obviously, the structure may be modified and changed in many respects without in the least departing from the spirit and scope of the invention as defined by the appended claims. The invention, therefore, is not limand having a retaining lip to overlie the base flange of a trackrail'seated in said channel and a lug below said'lip to underlie said base flange of the track rail in spaced relation thereto.

2. In a railway structure, a cross tie having a transverse rail seating channel therein, said tie having a socket contiguous to said rail seat ing channel, the inner end wall of said socket being substantially perpendicular and coincident with the adjacent wall of said channel,

and the outer end wall of said socket being upwardly flared, and a rail securing device comprising a block whose body portion is a counterpart of said socket and being detachably insertable therein, said block having a lip to overlie the base flange of a track rail seated in said channel and a lug below said lip to underlie said base flange of the track rail, and means for detachably securing said block in said socket.
